IFT FQB SUCKER RODS, PIPES, AND THE LIKE.

.a piieaaon filed December 1', 1924. Serial No. 753,381..

My invention relates to fishing tools and more particularly to suckerrod or pipe lift and to a combination of slips for en gaging rods andpipes nd a pipe or sucker rod lift; and the object is to provide a newfishing tool and particularly to provide a Combination fishing toolwhich is adapted to engage and lift rods and pipes and to lift a suckerrod by means of the weld or square. another distinguishing feature ofthis invention is that the lifting member is not supported by springsand rivets in operation. Other objects and advantages will be fullyexplained in the following description and the invention will be moreparticularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of thisapplication.

Fig. 1 is a side elevation of the combination tool. F 2 is an enlargedview, showing a vertical section of, the lift and the shoulder for thelift. 3 is a plan view of the lift'and the casing therefor, showing theshoulder or base for the lift; Fig. 4 is an inverted. plan view ofthelift. Fig' 5 is a horizontal section of the lift casing above theshoulder or base.

Similar characters of reference 316L156; to indicate the same partsthroughout the several views.

The vuppermember 1 of the toolis provided with slips 2 for pullingv rodsand pipes and the slips 2 are forced downwardly by a spring 3. The lowermember 4t includes the casing 4; for the lift 5. The lift 5 comprises abody having two arms 6 which constitute the grab and an attaching shank7. The lift 5 is pivotallyconnected to the casing t which has a verticalslot 8 therein to permitthe operation of the lift. The lift 5 ispivotally connected to the casing a by a pivot bolt 9. A spring 10 iscoiled about the bolt 9 and one end is inserted in a hole in the seat 11and the other end bears against the upper side of the lift 5 for holdThe object is to provide a positive means for holding the lift down andmaking certain the falling of thelift to engagethe sucker rod. Means areprovided for supporting the lift so that there will be no strain on thecasing land crescent shaped. The lift the throat 15.

5 has supporting members 13 which rest on I the base 12 when pulling asucker rod. The

general passage 14: through the casings is olf-set relative to thecasing l so that the .weld or square or box or pm of a suckerv soon asthe larger members of'the sucker rod and of the pipe pass above the lift5, the spring 10 will throw the lift 5 down- 'wardly so that it willengage the sucker rod below the weld or box and, if a pipe, the liftwill engage the pipe belowthe collar, so that the arms 6 will lift thesucker rod or pipe out of the well. The weld or box of the sucker rodand collar of a pipe cannot pass back .downwardly below the lift whenonce they have passed above the lift. The sucker rod or pipe'will becaught in The lower end of the casing t has a longer beveled portion. 16on that slde of the casing 4': below the shoulder 12 and a shorterbeveled portion 17 for aiding in centering the articles to be pulled inthe passage 14.,

lVhat I claim, is,---

l. A. fishing tool having a casing provided with a passage for the headsof sucker rods and for the passage of pipes and a crescentparts may bemade without departing from shaped shoulder offset in one side of saidpassage, a lift pivotally mounted in one side of said casingabove saidshoulder and provided with arms for catching under the welds of suckerrods and under the collars of pipes for lifting purposes, and shouldersdepending from said lift on-both sides of the pivotal connection andflat on the bottom edges and resting on said crescent-' shaped shoulderto support said lift on said shoulder.

2. A fishing tool having a casing provided with a passage off-set in oneside of said casingffor the'heads of sucker rods and for the passage ofpipes, a flat crescentslinpml shoulder exiemiing: the gzji'eziioi' poi--[ion about said passage, :1 lift pivotziiiy mounted in one side ofi saideasing above said shonidei' and held yioldingi'y on said Hhoukie' andPI'OVidQ-(i with arms for Quichin; under the T311154 of sucker rods andunder the collars of pipes, and flat bottomed shoi'ili'lorsi dependingfrom said lift and adopted ('0 rest on said crescenhshupod shoulder tosupport said lift on said shoulder and for preventing strain on saidpivotal connection.

In testimony whereof I set my hand, this 24th day of November, 1924.
